United States Patent 3,182,879 S'IAPLING DEVICE Arthur Dritz, 171 Beach at 125th St., Rockaway Park, N .Y. Filed Apr. 6, 1962, Ser. No. 186,827 2 Claims. (Cl. 227-119) This application is a continuation-in-part of application Serial No. 57,668 filed Sept. 22, 1960, now abandoned.

This invention generally relates to a novel tool for applying a fastening device to a single sheet or a plu- In one embodiment, this invention relates to a novel tool for applying fastening devices in the nature of pins to two or more layers of material.

FIGURE 1 is a view of a pinning device in accordance with this invention which is particularly suitable for fastening sheets of material together;

FIGURE 2 is a fragmentary view of the pinning device shown in FIGURE 1 as the hinged arm is placed in operative position;

FIGURES 36 are fragmentary views of a pin protector piercing arm useful in connection with the device shown in FIGURES 1 and 2;

FIGURES 7 and 8 are views of textile material containing a pin in accordance with this invention.

According to an embodiment of my invention sheets or layers of material may be fastened together with substantially straight fastening members. Referring to FIG- URE l a housing 50 is adapted to contain a plurality of fastening members 51 which may be fed toward the outlet end 53 of housing 50 in any known way, and for instance by a spring loaded feeder member 54. As the fastening members 51 are pushed toward the outlet end 53, they eventually come into alignment with outlet opening 55. Also aligned with this opening is plunger 56 which can be moved in the direction of arrow E by manual pressure upon arm 59 and which preferably then returns in the direction of arrow F by means of spring 58. When plunger 56 is pressed in the direction of arrow E, a fastening member 51 will be displaced outwardly through outlet 55. The described mechanism can therefore satisfactorily function as a straight pin dispenser, particularly when the pin consists of a fairly rigid metallic material.

However, when it is desired to employ fastening means conisting of a flexible material such as rubber or plastic, modifications to the described structure are desirable. Such modification preferably includes a piercing and protective arm 60 which can take one of several forms. As shown in FIGURE 1 such an arm 60 can be hingedly connected (by hinge 61) to the housing 50. It may be swung from the position shown in FIGURE 1 to the position shown in FIGURE 2. Since arm 60 has a hollow interior cavity or channel, a flexible staple (e.g. rubber) can readily be forced therethrough with relatively little difliculty. The operation of this device can probably be made somewhat clearer by referring to FIGURES 3 and 4, wherein in FIGURE 3 the arm 60 is shown as piercing layers of material 62 and 63 while a flexible staple is contained therein. When arm 60 has been inserted to the desired extent, the halves of the arm can be manually spread apart to the position shown in FIGURE 4. (Those skilled in this art would have no difliculty in devising ways for doing this mechanically rather than manually.) Plunger 56 can then be actuated or pushed further so that the flexible staple 51 will pass out between the open halves of arm 60 at the same time that the arm 60 is being withdrawn from the material. The arm 60 may open up for withdrawal, or the arm 60 may have an open end 65 to 3,182,879 Patented May 11, 1965 facilitate withdrawal as shown in FIGURES 5 and 6. The flexible staple 51 may be provided with a head 66 so as to facilitate holding in place. It will be obvious that plunger 56 must be long enough to extend to the outer end of arm 60 when pressed to its innermost position (see FIGURE 6).

Depending upon whether the staple is flexible or fairly rigid the position of the pin 70in place may appear as shown in either FIGURE 7 or 8. p

In conclusion, while the foregoing specification and drawing describe the construction, operation and use of one preferred embodiment of the instant invention, it is to be understood that I do not intend to limit myself to the precise constructions and arrangements herein disclosed, since the various details of construction, form and arrangement may obviously be varied to a considerable extent by anyone skilled in the art without really departing from the basic principles and novel teachings of this invention and without sacrificing any of the advantages of the invention, and accordingly it is intended to encompass all changes, variations, modifications and equivalents falling within the scope of the appended claims.

What is claimed is:

1. A pin driving device for driving substantially straight pins through one or more layers of material, comprising in combination:

(a) a magazine for holding a plurality of pins in sideby-side relationship,

(b) said magazine having an outlet end and an outlet opening in said outlet end through which pins are adapted to be ejected in a sequential manner,

(0) means for forcing the pins within said magazine toward the said outlet end of said magazine,

(d) said magazine having an inlet opening in said magazine that is axially aligned with said outlet opening,

(e) a plunger means that is positioned adjacent the inlet opening in said outlet end of the magazine,

(1) said plunger means being movable into the inlet opening in said magazine along a line that substantially coincides with the axis of said inlet and outlet openings so as to eject the lowermost pin from the magazine,

(g) an elongated hollow pin guard and protector positioned adjacent the outlet end of said magazine in axial alignment with the outlet opening in said magazine, said pin guard and protector being adapted to surround and protect pins during the course of their ejection from said outlet opening by said plunger means,

(h) 7 said plunger means being long enough to drive the forward end of said lowermost pin completely through said outlet opening and through said hollow guard and protector.

2. A pin driving device according to claim 1 wherein said elongated hollow pin guard and protector has an outer pointed end and is split longitudinally into two half sections that can be spread apart so a pin can be forced out between the open halves.
